Is it true ? One Quick and Dirty (TM) solution is given by the use of two different objects: one parsed function and one FEFieldFunction, then sum the results together. It is not as flexible as having the expression parsed at run time, but it is quick enough for most uses... Maybe you could be more specific on what you want to do?
